MAX SARFERT, OF PHILADELPHIA, PENNSYLVANIA.

PROCESS OF TREATING HOSIERY.

SPECIFICATION forming part of Letters Patent No. 667, 142, dated January29, 1901. Original application filetlMarch 13, 1900, Serial No. 8,489.Divided and this application filed October 12,1900. Serial No. 32,831.

(No specimens.)

To all whom it concern:

Be it known that I, MAX SARFERT, a citizen of the United States,residing in the city and county of Philadelphia, in the State ofPennsylvania, have invented a new and useful Improvement in Processes ofTreating Hosiery, which improvement is fully set forth in the followingspecification.

My invention consists of a process for treating hosiery for the purposeof removing the nap or lint from the surface thereof to produce what isknown as a silk or lisle finish, this application being a division of myapplication for patent for a process for giving a silk or lisle finishto hosiery or knit goods filed March 13, 1900, Serial No. 8,489, and Ido not therefore claim in this application the process described andclaimed therein.

I have found that the nap or lint on the surface of a stocking-forinstance, a cotton stockingcan be removed most effectually if thestockingis stretched or distended so that the threads are spread apart.In this way the flames or other singeing medium employed can reachsubstantially every fiber that forms this nap or lint, it being apparentthat when the stocking is in its normal or unstretched state the flameor other singeing medium cannot reach all of these fibers forming thenap or lint.

In carrying out my process I stretch the stocking over a board or formerof the kind familiar to those skilled in the art of dyeing which servesto stretch or distend the stocking, so that its threads are spread orseparated or pulled apart. The stocking thus stretched or distended onthe board or former is passed through the singeing-machine and thefibers forming the nap or lint are removed by the sin geing operation.In my said application for a patent for a process for treating hosiery Ihave setforth the manner in which this singeing process can be mosteffectually accomplished and which consists in treating hosiery beforesingeing so that the nap or lint can be more effectually removed whenthe stockingis singed-for instance, by first saturating the stockingwhen white or in its natural condition in a'solution consisting of thefollowing ingredients-namely, chlorid of soda or chlorid of potash, onepound; blue stone, one-half pound; anilin salt or anilin oil, four orfive pounds. Said solution is known as an anilin-black solution and isthe first step in the process of dyeing goods fast black. After thoroughsaturation the goods are dried in the atmosphere and are then in anoxidized state. It is while they are in this oxidized state that theirthreads are distended or pulled apart by being stretched upon a board orformer and passed through the singeing-machine to remove the nap orlint, it being noticed that the board or former acts as a backing fortemporarily and conveniently handling a stocking while being subjectedto the singeing action and readily removing it therefrom. After thestockings are thus singed they are finished, the finisher or finishingagent being, for instance, chrome of soda or chrome of potash, thisbeing the concluding step in a process of dyeing goods fast black.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The herein-described process for treating a stocking, which consistsin stretching or distending said stocking, whereby the threads areseparated or pulled apart, and then singeing the same.

2. The herein-described process for treating hosiery, which consists instretching hosiery over a former, whereby the threads thereofareseparated or distended, and then singeing said hosiery.

3. The herein-described process for treating hosiery which consists ininitially distending the hosiery and then singeing the same.

4. The herein-described process for treating hosiery Which consists ininitially distending the hosiery laterally and then singeing the same.

5. The herein-described process for treating hosiery which consists instretching the same on a former, whereby said hosiery is retained insubstantially a right line during the act of singeing, and then singeingthe same.

6. The method of treating hosiery, which consists in stretching the sameon a former,

and then singeing it on its surface and between the stitchesthereofiwhile in a stretched condition and held on said formerasabaeking.

7. The herein-described process for treating hosiery which consists insingeing the same while the fabric is abnormally stretched or distendedin every direction.

8. The herein-described process for treating hosiery which consists inprimarily distending the fabric in every direction, wherebysubstantially every fiber forming the nap or lint can be reached by asingeing agent, and next singeing said hosiery.

9. The herein-described process of treating hosiery which consists inabnormallystretching the fabric in every direction whereby MAX SARFERT.
